"This piece was a big aha moment for me. I grew up and live near Muir Woods, and there’s that big tree ring near the entrance, which I was always so gobsmacked by. This tree is visualizing time! They illuminate how the trees are a witness to human history. But it was always so patriarchal or colonialist, with lines like “Christopher Columbus discovered America” or “the Battle of Hastings.” However, I also felt like those timelines tell a colonialist and patriarchal story. The feminist history tree ring imagines what alternate histories could be told.I remember thinking, I want to see a feminist history tree ring! I need to see that! And I want my daughters to see that! I wanted everybody to see that!
The science of tree ring dating is called dendrochronology. So I called this piece Dendrofemonology: A Feminist History Tree Ring. In these artworks I’m playing with both dendrochronology and time, because I’m thinking about how these trees have lived thousands of years. So many monuments are made out of stone and they last too long. They’re about ideas that are old and dated. This timeline represents the past, the present, and where we want to go."
Watch our new seven minute film which explores the creative process and the ideas behind the sculpture and moveable monument, Dendrofemonology: A Feminist History Tree Ring.
Dendrofemonology: A Feminist History Tree Ring sculpture debuted as part of Tiffany Shlain's Human Nature exhibition in The San Francisco Ferry Building's Shack15 in November, 2022. A print of the artwork was part of the de Young Open at the de Young Fine Art Museum in San Francisco Sept 2023. The sculpture then was installed on the National Mall in Washington DC Nov 1-4, 2023, for a feminist art activation. This moveable monument then traveled to Madison Square Park, in NYC for A Mobilization of Women's Rights and the Planet September 21st, 2024. A framed print edition was part of the the "Artists for Kamala" benefit auction, an online fundraiser to support Vice President Kamala Harris's presidential campaign, featuring works by artists including Jenny Holzer, Jeff Koons, Amy Sherald, and Simone Leigh. Dendrofemonology was also part of Shlain's solo exhibition You Are Here at Nancy Hoffman Gallery in fall of 2024. It then traveled to be on view at the Women’s Art Center of the Hamptons. It currently is installed at 21c Museum Hotel St. Louis's year long exhibition of contemporary feminist art The Future is Female. This exhibition also includes Mickalene Thomas, Zoë Buckman, and Jenny Holzer. An edition will also be on view for Shlain's joint exhibition Ancient Wisdom for a Future Ecology: Trees, Time & Technology at di Rosa Center for Contemporary Art's San Francisco's Minnesota Street Project Arts Campus opening on Jan 20, 2026.
